ABSTRACT

A method of gluing a single surface of a shoe contains a first-stage processing and a second-stage processing. The first-stage processing includes a sole bonding having a first washing and polishing step, a first surface modifying step, a glue spraying step, and a sole adhering step. The second-stage processing includes a second washing and polishing step, a second surface modifying step, and an adhesive agent coating step. A vamp and sole processing includes a vamp treating step, a treatment agent coating step, and an adhesion forming step. A shoe midsole on which an adhesion promoter is sprayed and a shoe outsole on which adhesive glue is coated are adhered together to finish a shoe sole. The adhesive glue is coated on an upper surface of the shoe sole to adhere with a lower adhering surface of a vamp on which a treatment agent is coated, thus finishing a shoe.

FIELD OF THE INVENTION

The present invention relates to a method of gluing a single surface ofa shoe in which a treatment agent is made of a reinforcing agent andadhesive glue and is coated on a lower adhering surface of a vamp tosimplify a treatment agent coating step.

BACKGROUND OF THE INVENTION

Referring to FIG. 1, a conventional method 1 of gluing a shoe midsole, ashoe outsole, and a vamp contains a washing and polishing step 10, asurface modifying step 11, a gluing step 12, and an adhering step 13.The washing and polishing step 10 is to wash or polish the shoe midsoleand the shoe outsole, thus eliminating a release agent which attaches onthe shoe midsole and the shoe outsole. The shoe midsole and the shoeoutsole are dried, and the surface modifying step 11 is to modify threeadhering surfaces of the shoe outsole, the shoe midsole, and the vamp byapplying a surface modifier on the three adhering surfaces. The gluingstep 12 is to coat glue on the three adhering surfaces of the shoeoutsole, the shoe midsole and the vamp, and then the shoe outsole, theshoe midsole and the vamp are baked and adhered together in the adheringstep 13, thus finishing a shoe.

However, before adhering the shoe midsole and the shoe outsole together,the glue is manually coated on two adhering surfaces of the shoe outsoleand the shoe midsole, thereby causing gluing complexity and poorproduction efficiency.

The present invention has arisen to mitigate and/or obviate theafore-described disadvantages.
